Abstract

The utilization of solar energy through solar panels as a source of electrical energy for households and street lighting is increasing rapidly. However, solar panels face problems related to working temperature. When the absorption of solar radiation is too high, it results in a decrease in efficiency. High temperatures cause solar panels to produce lower energy than in cold conditions. Therefore, the purpose of this study was to explore the effect of aluminum cooling fins on solar panels, with variations of fin inclination angles of 30° and 45°, and compared with panels without a cooling system to reduce the working temperature of solar panels by using cooling fins and air blowing media. The results showed that at an angle of 30°, the panel temperature was 43.60°C at the 13th iteration, with a temperature drop of about 3.13%. At an angle of 45°, the temperature obtained was 41.80°C with a temperature drop of about 6.68%. Meanwhile, the uncooled condition reached a maximum temperature of 44.40°C. No cooling causes the panel temperature to be higher, and the 45° angle provides a better cooling effect than the 30° angle, although the difference is not very significant when compared to the uncooled condition.

Abstract

The metal casting industry faces global challenges in managing greensand dust waste containing silica and clay from bentonite and silica sand, which has the potential to cause environmental and health impacts. Therefore, this study analyzes the effect of greensand dust utilization on the characteristics of greensand molds made from return sand. Additionally, this study aimed to ascertain the ideal percentage of dust required to attain the maximum green compression strength (GCS) value. This study examined dust usage variations of 0%, 15%, 30%, and 45% relative to the weight of bentonite. When calculated based on the weight of sand, these proportions translate to 0%, 0.09%, 0.18%, and 0.27%. The sand underwent several tests, including assessments for compactibility, moisture, permeability, grain fineness number (GFN), green compression strength (GCS), dry compression strength (DCS), wet tensile strength (WTS), active clay, volatile combustible material (VCM), and loss on ignition (LOI). The application of dust from greensand molds in the metal casting sector suggests that this dust can effectively replace bentonite. The ideal formulation for the molding sand includes 100% return sand, 0.42% bentonite, 0.18% dust, and 2.9% water. Specifically, the most efficient binder combination consists of 70% bentonite and 30% dust. This particular mixture achieves the highest GCS of 13.4 N/cm². A greater GCS value signifies that the molding sand possesses an improved ability to withstand the pressure from the molten metal during the pouring process.

Abstract

This research aims to evaluate the heat transfer characteristics of a radiator using silicon dioxide (SiO2) nanofluid. The study was conducted experimentally, and the research scheme consisted of a water/nanofluid reservoir tank, a heater for water heating, a pump to circulate water/nanofluid to the radiator, and a cooling fan to dissipate heat. The research results indicate a 15% increase in the average heat transfer coefficient at a temperature of 60°C. The maximum heat transfer enhancement occurred at a concentration of 0.2%, with a 21% increase at a Reynolds number of 3200 at a temperature of 60°C. At a temperature of 70°C, there was an 18% increase in the average heat transfer coefficient. The maximum heat transfer enhancement occurred at a concentration of 0.2%, with a 24% increase at a Reynolds number of 3200.

Abstract

This study explores the potential of nanoscale silicon carbide (SiC) particles synthesized from rice husk ash to enhance light absorption characteristics in solar panel applications. The SiC particles were produced by burning rice husks, followed by purification and division into two groups: one group underwent heat treatment at 400 °C, while the other was kept untreated for comparative analysis. High-Energy Milling (HEM) for 60 hours was used to reduce the particle size of selected samples. Comprehensive characterization was performed using Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and UV-Vis spectroscopy in the wavelength range of 200–1100 nm. The results of the study indicate that heat-treated SiC exhibits significantly reduced agglomeration and better particle dispersion compared to untreated samples. FTIR analysis confirmed the presence of additional functional groups (C=C and O–H) in the treated SiC, which contribute to surface chemical modification. Most importantly, the UV-Vis spectra show that the treated SiC maintains consistently higher absorbance values (0.5–0.6) in the visible to near-infrared region (400–1100 nm), whereas the untreated SiC exhibits a decreasing trend (0.4–0.2). These findings suggest that thermal processing can enhance the optical performance of SiC nanoparticles by improving dispersion and introducing functional groups that strengthen light-matter interactions. The superior absorption characteristics of the processed SiC demonstrate promising potential as an additive or nanostructured layer to improve photon capture and overall efficiency in photovoltaic devices

Abstract

Mild steel dampers are widely utilized as energy dissipation devices due to their ductility and stable mechanical behavior. This study presents a numerical investigation of the effects of plate thickness and material variation on the mechanical performance of an H-type mild steel damper using nonlinear finite element analysis. The model is developed in ANSYS with three-dimensional solid elements, incorporating material and geometric nonlinearity to capture structural response under loading. Two parametric studies are conducted, including plate thickness variations (15 mm, 20 mm, 25 mm, and 30 mm) and material variations (structural steel, grey cast iron, and aluminum alloy). The mechanical behavior is evaluated based on deformation, equivalent stress, and strain distribution along the damper height. The results show that increasing plate thickness significantly reduces deformation and strain while improving stress distribution, indicating enhanced structural stiffness. However, excessive thickness may limit deformation capacity. In terms of material performance, structural steel exhibits the most stable behavior with low deformation and controlled stress and strain distribution. Aluminum shows higher deformation and strain due to its lower stiffness, while grey cast iron demonstrates limited ductility and higher stress concentration. An optimal configuration is identified at a thickness of 20-25 mm using structural steel, providing a balance between stiffness and deformation capability. These findings contribute to the design optimization of metallic dampers for structural applications.
